Continual Improvement Process
The Continual Improvement Process is how we achieve ever-increasing levels of operational performance and customer satisfaction.
The concept is based upon the premise that in order to meet and exceed customer needs a company must continually improve. The Crowley steps of continual improvement are:
Assess, Plan, Execute, Sustain
The achievement of ISO conformance helps to document Crowley’s Commitment to continuous improvement. By optimizing key processes and recording the procedures necessary to meet our customers’ requirements, Crowley strives to deliver on our service commitment of “First Time, every Time” quality.
Certifications and Standards
Crowley’s Integrated Management System is designed to meet internationally recognized standards and includes documented policies, procedures, and work instructions that guide how we operate safely, sustainably, and with excellence.
We maintain conformity with the following ISO standards:
ISO 9001 – Quality Management
Focuses on meeting customer requirements, enhancing customer satisfaction, and driving continual improvement across our operations.
ISO 14001 – Environmental Management
Addresses the environmental aspects and impacts of our activities, ensuring responsible stewardship, compliance with applicable regulations, and support for our sustainability commitments.
ISO 45001 – Occupational Health & Safety Management
Establishes a framework for identifying and controlling health and safety risks, reducing workplace incidents, and creating safer working conditions for all employees and contractors.
ISO 27001 – Information Security Management
Ensures the protection of information assets through systematic and cost-effective controls that preserve confidentiality, integrity, and availability.
Together, these standards form the foundation of Crowley’s approach to quality, safety, environmental protection, and information security.
Independent Certification and Ongoing Assurance
Crowley’s ISO certifications provide customers and stakeholders with independent verification that our management system conforms to the requirements of each standard. To maintain certification, accredited third‑party organizations conduct regular audits to review system performance, confirm compliance, and validate continuous improvement.
PDF copies of our certificates are available via links below.
Throughout the Crowley fleet, the international standard set for safe operation of ships and for pollution prevention is symbolized by certification of the International Safety Management (ISM) Code.”
Regardless of the vessel’s tonnage or operational area, across Crowley’s fleet you will find all vessels operated in the spirit of the ISM, diligently practicing safety of people, property, and the environment.
The Crowley companies are committed to full implementation of an environmental, safety and quality assurance management system which includes ISO/ISM and the American Waterways Operators (AWO) Responsible Carrier Program (RCP). The requirements of the AWOs program have been combined with the elements of the ISO/ISM requirements for tug and barge operations. Comprehensive operating policies and procedures are established to protect the safety of employees and protect the environment while providing marine transportation for our customers.
The AWO is the largest trade association for the US tug and barge industry. The Responsible Carrier Program is an established code of practice for association membership, which was unanimously approved in 1994 by the AWO Board of Directors.

Quality Assurance
We provide superior quality service and meeting or exceeding customer expectations at every turn. This dedication is exemplified by our Quality Assurance commitment, which states “we will provide services for our customers in conformance with established procedures and requirements. Our work will be done right the first time and every time.”
As part of this effort, Crowley has developed a Management System that serves as the foundation of our corporate standards while defining processes to prevent deficiencies and encourage continual improvement. This system is based upon four key elements: Safety, Environment, Quality and Security. The details of the system and the four key elements are outlined in our Management System Tier One Manual.
Our quality management system includes annual internal vessel, facility and office audits; third-party verification audits; document control and monthly measurements of key metrics.
